How do you find the inventor on Game Show Island?

Answer 1

1. give the man that needs soap the nickel
2. he will give you heat ray goggles
3. use those and go to the club on the top floor on the left
4. he will go up in the air vent
5. go outside and use the fan to help you up the club then go to the window that's bolted in
6. use your toolbox to unscrew it
7. enter and you will find him.

Answer 2

He is hiding in the attic of the Club, but you can't find him right away. Get the toolbox from the Boutique roof, go to the factory and fix the belt, to get a fan, which you can use to cool the robot Club owner. Take the nickel he gives you to the homeless guy past the factory.

After you get the heat vision goggles, go upstairs in the nightclub, past the "robots only room" and look in the ventilation shaft above the bar at the far left using the goggles. Then you can go outside and enter the small door at the upper right side (use the fan to fly up).

Answer 3

Once you find the inventor with the heat vision googles, exit the night club and go up to the entrance to the heat vent outside. Use the toolbox to unjam the door and chase him.
